The truth is, Linux is the future and Microsoft is a dead duck. I disagree with the switch to Ubuntu, instead a better choice would be Xubuntu (Still in the Ubuntu family).
jimmysmitty, That's pure ignorance. DirectX is a Windows Only API. OpenGL is the standard that runs on ALL platforms. At PAX 2013, developers recommended abandoning DirectX due to it being a Microsoft only API.
Linux is about Community, chances are your question is already answered on places like askubuntu. You do NOT need support. One guy asked about Games, you have the Humble Bundle, Desura and Steam. There are thousands of games to choose from. If you like FPS, Linux has the most of any OS.
Steam makers, Valve are moving to Linux guys. Windows is becoming a closed platform (walled garden) where you can only use the things Microsoft wants you to use. If you enjoy Steam, Windows and Mac are being left behind.
Gabe (Valve/Steam) announced at LinuxCon 2013 that they believe Linux is the future platform for Gaming. People, you already use Linux in your Phones, TV, Router etc. It's everywhere!. In closing, I suggest if you are ignorant (like those here) then stop replying about things you know nothing about.
I used Windows for 15 years until I switched to Xubuntu last year. I will never go back to Microsoft's chains of forced upgrades and security ridden Windows filled with NSA backdoors.
